1 Claim.

My invention relates .tonewv land useful im` provements in snapfasteners andA has-for an object to provide a fastener. consisting ofv asocket member anda stud member,the socket member being formed ofvasingle piece of metal and the stud memberformed of but .two pieces ofmetal.y

Both the stud memberand .the socket member are fastened to theirrespective carrying mediums by an eyelet, which eyelet may be usedeither with the studmember or a socket member so that in the manufactureof thelsnap fastener .there are but four different pieces toA be shaped,one lbeing the eyelet, which may be used foreither the socket member orthe stud member, the socket formed of one piece and the stud memberformed of two pieces, thus making for an economical construction.

Still another object of the invention is to provide a snap fastenerwhich is strong and eicient in service and whereineach part, that is,the socket member and the stud member `are held in place by eyelets thatare headed in position. Also, both the socket and the eyelet are so madethat the heading tool may easily pass through the socket and/ or thestud member to clench the respective parts to their respective carryingmediums.

Still another object of the invention is to provide a snap fastener thatmay be readily separated by an intentional pull, and on the other hand,will snap with a loud click when the parts are fastened, showing theuser that the fasteners are in their closed or locked position.

With these and numerous other objects in view, the invention consists incertain new and novel arrangements as will be hereinafter more fullydescribed and pointed out in the claim.

Referring now to the drawing showing the preferred embodiment:

Fig. 1 is a sectional View on an enlarged scale showing the stud andsocket member in locked engagement and secured to their respectivecarrying mediums,

Fig. 2 is a 'bottom plan view of the stud member,

Fig, '3 is a top plan view of the socket memberA Referring now to theseveral views` and to Figs'. l and 4 for the moment, there isshown-thefstud member I which is formed of metal having 'the'delsiredthickness and other characteristics that-go to make up a snap fastenerstud having a certain amount of resiliency. n

. It will ybe seen that this member consists of the body plate 2 whichis curved downwardly and outwardly as at 3, while centrally yof .thesame there is pressed or formed .the Adownwardly eX- tending cylindricalwall 4 at the lower end `ol which is a semi-circular shaped portion or'annulus to form the head or ball 5. l

The bottom of the 'Iball 5-is openasat.while the walls of the annulus 5and the cylindrical wall 4 are slotted as at 'I so that when this heador ball 5 is tted into the socket member I2, which is severalthousandths in diameter less than the external diameter of the head ofthe stud, the several sections of the ball 5 will be compressed and snapinto the socket I2. On the other hand, the head will again be compressedas the stud is pulled from its socket as will be understood.

The outer peripheral portion 8 of the body portion 2 is first bent up tothe dotted line position as shown in Fig. 4 so that the top plate 9which has the outwardly extending dished portion I0, may be placed inposition and then the rim 8 bent backwardly to tightly grip this plate 9in place.

This holding plate 9 is also provided centrally with the opening II asit is within this opening that the eyelet about to be mentioned ispassed and then headed.

Thus, it will be seen that the stud member consists of only 2 parts,that is, the bodi7 2 which may be easily stamped and rolled into form,and the top plate 9 which is readily assembled and clamped into positionto thus form the complete stud mem-v ber.

Referring now to Fig. 5, it will be seen that the socket member I2 isalso exceedingly simple in construction, it having a slightly flared rimI3 that extends upwardly to the top of the socket I4, and here the metalis bent back on itself as at I 5 and is slightly arcuated or cuppedcorresponding in circular outline to the annulus 5 of thestud member.

The bottom wall I6 extends in a horizontal position and is provided witha central opening I 1.

As heretofore, mentioned, the diameter of the mouth I2' of the socketmember I2 is less than the external diameter of the head of the stud sothat the stud will be constricted as it is forced into its socketmember.

Referring now for the moment to Fig. 7, there body of the stud member.

' is shownan eyelet IB which has'a relatively large integral head orplate I9 which is slightly dished in cross section and has the centercylindrical wall 20. The diameter across the head is substantiallythediameter across thesocket member and just slightly less than thediameter across the By providing a head of this size there is plenty ofgripping surface to the cloth and itwill be understo'od that if desired,

a trade mark or insignia or otherV indicia might Y be stamped in thishead.

Now to secure the stud member I to its carrying medium 2|, the eyeletsI8 will be fed in an attaching machine (not shown) to an anvil orVattaching station and.Y thestud Ymemberswill also be fed to the samestation, while between the two parts Will be positioned the cloth 2 I.

' and readily manufactured andV presents no diffi- Aheading pin orYV diemay then be passed Y through the bottom opening in the stud and afterVthe cylindrical wall 20 has cut a hole in thecloth 2| and passedthrough the opening I I in the plate of the stud member, the bottom edgeV22 of the eyelet'will be rimmed or headed as may be clearly seen inFig. 1. 1 y

The stud lmember is now tightly clamped between the head of the eyeletI8 and the surface of the plate V9V of the stud member.

In a like manner, it is asimple matter to secure the socket member YI3to its carrying medium 23,

asafterV the eyelet I8 has been passed through Y cult problems inattaching as both the stud I and the socket I2 member may be readilysecured to their carrying mediums by passing theA eyelets I8 through thereceptive openings and then heading the eyelets.

Y In use, the stud member I will quickly and readily snap within itssocket I2 and until intentionally'removedbytiltingone member the respectto the other, there is little possibility of the parts'becomingseparated. Also, by providing an eyelet I8 .with the relatively largehead there is little likesaid member comprising a body portion having adownwardly and outwardly flared rim, arperforated holding plate slightlyless 'in diameter mounted on the said body portion and the metal oftheflared rim 'bent back on itself clamping said plate in position, acentral dependent vcylindrical I wall in the body portion, the lowerportion of the its cloth and through the opening II of the socket lmember, it will be headed as may be seen at12 in Fig. 1. 4 a v -From theforegoing it fastener above described is one that may be easily will beseen that the snap Wall provided with a projecting annulussemicircularin cross section and the annulus provided with a plurality of spacedslots, an eyelet adapted to be forced through a carrying medium and'headed against the inner surface of said aforementioned plate.
